This three-chapter guide was the result of a curriculum development project undertaken by the North Carolina Department of Community Colleges to align vocational curricula with valid, on-the-job performance requirements. It outlines a suggested curriculum designed to train individuals for career opportunities in horticulture. Chapter I describes project activities, including a survey of horticulture occupational programs; a survey of nursery workers in North Carolina to identify career opportunities in the field; the development and validation of a list of tasks for each career opportunity; and an analysis of each task to determine the necessary knowledge, skills, and attitudes to complete it. Chapter II presents job descriptions and associated tasks for 16 entry- and advanced-level positions within the horticulture field. Chapter III contains the curriculum guide, providing: (1) a suggested series of courses for a seven-quarter period; (2) brief descriptions of these courses; (3) a list of electives for Horticulture Technology students; (4) guidelines for faculty and staff selection and certification; (5) guidelines for facilities, equipment, and instructional aids; and (6) 19 course outlines which specify prerequisites, performance objectives, course content, and suggested texts. Extensive appendices outline survey results and detail the competencies and criterion measures associated with identified tasks. (JP)
